Ce doctorat trouve son origine dans la compréhension des prises de décision et des comportements collectifs des animaux. Comment ces derniers parviennent-ils à effectuer des choix collectivement ? Comment les membres d’un groupe procèdent-ils pour synchroniser leurs comportements spatialement et temporellement ? Mon principal objectif a été de dégager, lors des déplacements collectifs et du fur rubbing chez le capucin moine, les évènements décisionnels dépendants de processus anonymes de ceux dépendants de processus liés à l’identité des individus et à leur réseau de relations sociales au sein du groupe. Dans les prises de décision collective relatives aux déplacements, les membres du groupe sont influencés dans leurs choix par leur identité sociale mais aussi par des mécanismes anonymes, de type mimétique. Le fur rubbing est également un comportement collectif dont les mécanismes sous-jacents incluent une dépendance interindividuelle de type mimétique. Des mécanismes similaires mettant en jeu des interactions entre individus basées sur des règles comportementales simples se retrouvent dans chacun des phénomènes collectifs étudiés. Ces résultats sont les premiers à démontrer l’émergence de prises de décision collective à partir de telles interactions anonymes dans un groupe de primates non humains. Ils permettent de faire le lien entre choix individuels et comportement collectif et de mieux concevoir comment un groupe de primates peut se coordonner, maintenir sa cohésion spatiale et synchroniser ses activités./How do animals reach collective consensus? How do group members spatially and temporally synchronise their behaviour? My main purpose was to demonstrate the respective roles of anonymous processes (contagion, mimetism) and individual-dependent processes (hierarchical rank, age, sex, kin, social relationships) in collective decision-making. During decision-making relating to collective movements, group members’ decisions depend on their social identity (individual-dependent mechanism) as well as anonymous processes. Fur rubbing is also a collective behaviour involving interindividual dependence with mimetic underlying mechanisms. We found similar mechanisms, involving interindividual interactions according to simple behavioural rules, in both collective phenomenon studied. These results are the first to demonstrate the emergence of collective decision-making based on anonymous interactions in a group of non human primates. They help to understand the link between individual choices and collective behaviour and to appreciate how a social group of primates maintain its spatial cohesion and synchronize its activities.

A l’arrivée des premiers colons à Assiniboia en 1811, le territoire n’est encore qu’un terrain de chasse pour les grandes compagnies de commerce des fourrures, qui obéissent aux codes d’une lex non scripta propre au milieu et à l’économie des Territoires Indiens. La colonie dépend ensuite de la tutelle juridique de la Compagnie de la Baie d’Hudson, qui gère ses institutions légales et gouvernementales à l’abri d’interventions canadiennes ou britanniques. Jusqu’à son annexion au Canada en tant que province du Manitoba en 1869, Assiniboia est le seul district de l’Ouest canadien continental doté d’institutions législatives et judiciaires. Cette thèse analyse l’évolution de la loi et du droit dans la société métisse de la Rivière Rouge (Assiniboia). A travers les sources des fonds législatifs et judiciaires de la colonie, les récits, correspondances et journaux de dirigeants, de missionnaires et d’habitants d’Assiniboia, ce travail observe les usages de l’outil juridique et ses effets normatifs sur les colons. Cette étude postule qu’un demi-siècle après sa création, la Rivière Rouge est un espace légal hybride, où le droit coutumier coexiste avec le droit institutionnel. Cette recherche démontre l’importante participation de la population à sa propre gouvernance et l’établissement progressif d’un pluralisme juridique qui savait reconnaître et respecter les altérités sociales de la Rivière Rouge, où se rassemblaient des Eurocanadiens, des Autochtones et une majorité d’individus métissés et semi-nomades. Enfin, cette étude met en évidence le rôle fondamental des Métis et du métissage dans tous les processus de changements légaux du territoire. / This dissertation examines the evolution of law in Red River (Assiniboia) through the systems, ideas and events that informed the inhabitants’ concepts of rights, from the colony’s creation until its entry into the Canadian Confederation (as the province of Manitoba). Assiniboia was founded in 1811 in the unsettled Indian Territories which were used as hunting grounds by fur-trading companies, who developed the codes and practices of a lex non scripta on-site to regulate social norms, trade and competition. In the 1820s, the District of Assiniboia came under the management of the Hudson’s Bay Company and was placed under its jurisdiction, and, until the late 1860s, it was the only settlement of the western interior to have its own government and institutions. By looking at the legislative and judicial records of the district, the narratives, correspondence and journals composed by settlers, missionaries and rulers of Red River, this dissertation studies the uses of the law as a form of symbolic violence and a normative tool in the social context of the colony. This study contends that, half a century after its creation, Assiniboia was a hybrid legal space ruled simultaneously by customary and institutional law. It demonstrates the population’s active role in its own governance, and the gradual establishment of a legal pluralism that recognized and respected Red River’s multicultural society, one composed of French and English speaking settlers, Amerindians, and a majority of semi-nomadic people of mixed descent. Ultimately, this study highlights the fundamental role played by the Métis and their Native background in all of the changes to the territory’s legal system.

Le litige concernant la frontière de l’Oregon, ou la question de l’Oregon, est le résultat des revendications britanniques et américaines pour la région du Pacifique Nord-Ouest de l’Amérique du Nord pendant la première moitié du XIXe siècle. Le Royaume-Uni et les États-Unis ont des aspirations territoriales et commerciales sur cette région. La région est pour les Britanniques une zone d’exploitation pour le commerce de la fourrure pour la Compagnie de la Baie d’Hudson, tandis que les Américains y voient une région peuplée de fermiers. Le différend sur l’Oregon est devenu important dans la diplomatie entre l’Empire britannique et la république américaine. / The Oregon boundary dispute, or the Oregon Question, arose as a result of competing British and American claims to the Pacific Northwest of North America in the first half of the 19th century. Both Great-Britain and the United States had territorial and commercial aspirations in the region. For the British, the area was a fur-trading division of the Hudson’s Bay Company, while for the Americans the region was to be settled by farmers. The Oregon dispute became an important diplomatic issue between the British Empire and the American Republic.

At the end of the 18th century, Anglo Americans and Europeans entered the mouth of the Columbia River for the first time. There they encountered large villages of Chinookan and other Native Americans. Soon afterwards, the Chinookan People became involved in the global fur trade. Pelts, supplies, and native made goods were exchanged with fur traders, who in return provided Chinookans with a number of trade goods. Over the next 40 years, life changed greatly for the Chinookans; new trade and political alliances were created, foreign goods were introduced, and diseases killed large portions of the population (Hajda 1984; Gibson 1992; Schwantes 1996; Boyd 2011; Boyd et al. 2013). Additionally, fur trade forts, like the Hudson's Bay Company's (HBC) Fort Vancouver, were established. At these forts, new multiethnic communities were created to support the fur trade economy (Hussey 1957; Kardas 1971; Warner and Munnik 1972; Erigero 1992; Burley 1997; Mackie 1997; Wilson 2010). This thesis is an historical archaeological study of how Chinookan peoples at three villages and employees of the later multicultural Village at Fort Vancouver negotiated the processes of contact and colonization. Placed in the theoretical framework of practice theory, everyday ordinary activities are studied to understand how cultural identities are created, reinforced, and changed (Lightfoot et al. 1998; Martindale 2009; Voss 2008). Additionally uneven power relationships are examined, in this case between the colonizer and the colonized, which could lead to subjugation but also resistance (Silliman 2001). In order to investigate these issues, this thesis studies how the new foreign material of vessel glass was and was not used during the everyday practice of tool production. Archaeological studies have found that vessel glass, which has physical properties similar to obsidian, was used to create a variety of tool forms by cultures worldwide (Conte and Romero 2008). Modified glass studies (Harrison 2003; Martindale and Jurakic 2006) have demonstrated that they can contribute important new insights into how cultures negotiated colonization. In this study, modified glass tools from three contact period Chinookan sites: Cathlapotle, Meier, and Middle Village, and the later multiethnic Employee Village of Fort Vancouver were examined. Glass tool and debitage analysis based on lithic macroscopic analytical techniques was used to determine manufacturing techniques, tool types, and functions. Additionally, these data were compared to previous analyses of lithics and trade goods at the study sites. This thesis demonstrates that Chinookans modified glass into tools, though there was variation in the degree to which glass was modified and the types of tools that were produced between sites. Some of these differences are probably related to availability, how glass was conceptualized by Native Peoples, or other unidentified causes. This study suggests that in some ways glass was just another raw material, similar to stone, that was used to create tools that mirrored the existing lithic technology. However at Cathlapotle at least, glass appears to have been relatively scarce and perhaps valued even as a status item. While at Middle Village, glass (as opposed to stone) was being used about a third of the time to produce tools. Glass tool technology at Cathlapotle, Meier, and Middle Village was very similar to the existing stone tool technology dominated by expedient/low energy tools; however, novel new bottle abraders do appear at Middle Village. This multifaceted response reflects how some traditional lifeways continued, while at the same time new materials and technology was recontextualized in ways that made sense to Chinookan peoples. Glass tools increase at the Fort Vancouver Employee Village rather than decrease through time. This response appears to be a type of resistance to the HBC's economic hegemony and rigid social structure. Though it is impossible to know if such resistance was consciously acted on or was just part of everyday activities that made sense in the economic climate of the time. Overall, this thesis demonstrates how a mundane object such as vessel glass, can provide a wealth of information about how groups like the Chinookans dealt with a changing world, and how the multiethnic community at Fort Vancouver dealt with the hegemony of the HBC. Chinookan peoples and the later inhabitants of the Fort Vancouver Employee Village responded to colonization in ways that made sense to their larger cultural system. These responses led to both continuity and change across time.

At Cape Gantheaume, Kangaroo Island (South Australia), adult male, lactating female and juvenile New Zealand (NZ) and Australian fur seals regularly return to the same colony, creating the potential for intra- and inter-specific foraging competition in nearby waters. I hypothesised that these demographic groups would exhibit distinct foraging strategies, which reduce competition and facilitate their coexistence. I analysed the diet of adult male, adult female and juvenile NZ fur seals and adult male Australian fur seals and studied the diving behaviour of adult male and lactating female NZ fur seals and the at-sea movements of juvenile, adult male and lactating female NZ fur seals. Female diet reflected that of a generalist predator, influenced by prey availability and their dependant pups� fasting abilities. In contrast, adult male NZ and Australian fur seals used larger and more energy-rich prey, most likely because they could more efficiently access and handle such prey. Juvenile fur seals primarily utilised small lantern fish, which occur south of the shelf break, in pelagic waters. Juveniles undertook the longest foraging trips and adult males conducted more lengthy trips than lactating females, which perform relatively brief trips in order to regularly nurse their pups. Unlike lactating females, some adult males appeared to rest underwater by performing dives that were characterised by a period of passive drifting through the water column. The large body sizes of adult males and lactating females facilitated the use of both benthic and pelagic habitats, but adult males dived deeper and for longer than lactating females, facilitating vertical separation of their foraging habitats. Spatial overlap in foraging habitats among the age/sex groups was minimal, because lactating females typically utilised continental shelf waters and males used deeper water over the shelf break, beyond female foraging grounds. Furthermore, juveniles used pelagic waters, up to 1000 km south of the regions used by lactating females and adult males. The age and sex groups in this study employed dramatically different strategies to maximise their survival and reproductive success. Their prey and foraging habitats are likely to be shaped by body size differences, which determine their different physiological constraints and metabolic requirements. I suggest that these physiological constraints and the lactation constraints on females are the primary factors that reduce competition, thereby facilitating niche partitioning.

The lack of a chronological framework for 16th and 17th century northeastern North America has impeded local and regional cultural reconstructions. Based upon the changing style of 16th and early 17th century European glass beads and the settlement patterning of the Neutral Iroquoians of southern Ontario, a chronology has been created. It provides the means to investigate native and European cultural trends during that era, and within this dissertation three topics are examined--the development of the commercial fur trade and its archaeological manifestations, an archaeological definition of the Neutral Iroquoian confederacy, and changes in European material culture recovered from pre-ca. AD 1650 archaeological contexts throughout the Northeast.
